CROSS REFERENCE TO RELATED APPLICATION

The disclosures of Japanese Patent Application No. 2014-95029 filed on May 2, 2014 and Japanese Patent Application No. 2014-110879 filed on May 29, 2014 are incorporated herein by reference.

FIELD

The technology herein relates to an information processing system, an information processing device, a storage medium storing an information processing program, an information processing method and a storage device for performing near field communication.

BACKGROUND AND SUMMARY

Conventionally, there is a technology for performing communication between devices by use of near field communication such as NFC. By near field communication, communication between an information processing device and a storage device (so-called tag) starts in response to the storage device approaching the information processing device.

Conventionally, a storage device that is communicable with an information processing device by near field communication is merely used in a specific application program executed by the information processing device, and there has been room for improvement regarding the versatility of such a storage device.

Accordingly, this application discloses an information processing system, an information processing device, a storage medium storing an information processing program, and an information processing method, with which a storage device is usable in a more versatile manner, and such a storage device.

(1)

An example of information processing system described in this specification is an information processing system including a storage device; and an information processing device for performing near field communication with the storage device.

The storage device includes a storage unit storing application data usable in a predetermined application program and shared data usable in an application program regardless of whether or not the application program is the predetermined application program.

The information processing system includes an acceptance unit, a first processing unit and a second processing unit. The acceptance unit accepts an instruction regarding data read and/or data write from/to the storage unit from an application program to be executed by the information processing device. In the case where the accepted instruction is regarding the application data, under the condition that the instruction is from the predetermined application program, the first processing unit transfers the application data read from the storage unit to the predetermined application program. In the case where the accepted instruction is regarding the shared data, the second processing unit transfers the shared data read from the storage unit to the application program that issued the instruction regardless of whether or not the instruction is from the predetermined application program.

(2)

The storage unit may store identification information that is set for each of types of storage devices. The predetermined application program may include identification information that is set for a type of storage device which stores the application data usable in the predetermined application program. The first processing unit may determine whether or not the accepted instruction is from the predetermined application program based on the identification information read from the storage unit and identification information acquired from the application program that issued the instruction.

(3)

The storage unit may store identification information specifying at least one type of predetermined application program which can use the application data. The acceptance unit may accept, from the application program, the identification information corresponding to the application program that issued the instruction. The first processing unit may determine whether or not the accepted instruction is from the predetermined application program based on the identification information stored on the storage unit and the identification information acquired from the application program that issued the instruction.

(4)

The storage unit may store application data encrypted by a method which allows the encrypted data to be decrypted by the first processing unit and shared data encrypted by a method which allows the encrypted data to be decrypted by the second processing unit.

(5)

The storage device may have an external appearance representing, three-dimensionally or two-dimensionally, an object which appears in a virtual space generated by execution of the predetermined application program and which is represented by the application data and/or the shared data.

(6)

The storage unit may store, as the shared data, at least one type of data among identification information on the object, identification information on a group to which the object belongs, identification information specific to each of storage devices, and identification information representing the type of the storage device.

(7)

The information processing device may include a determination unit for, when near field communication is made possible between the information processing device and a storage device, determining whether or not the storage device is a permitted storage device, an access to which by the information processing device is permitted. In the case where it is determined that the storage device with which the near field communication is made possible for the information processing device is a permitted storage device, the acceptance unit may execute a process in conformity to the instruction from the application program to be executed by the information processing device.

(8)

The storage device may store at least a part of the shared data in a read-only area from which data can be read but to which data cannot be written, and may store the application data in a read/write area from which data can be read and to which data can be written.

(9)

The application data may be saved data of the predetermined application program.

(10)

Another example of information processing system described in this specification is an information processing system including a storage device; and an information processing device for performing near field communication with the storage device.

The storage device includes a storage unit storing shared data which is on an object appearing in a predetermined application program and which is usable in an application program regardless of whether or not the application program is the predetermined application program.

The information processing device includes a first processing unit and a second processing unit. The first processing unit executes a first process of, for executing the predetermined application program, outputting information on the object to an output device by use of the shared data read from the storage unit. The second processing unit executes a second process of, for executing an application program different from the predetermined application program, outputting information on the object to the output device by use of the shared data read from the storage unit, the second process being different from the first process.

(11)

The information processing device may further include a determination unit and a permission unit. When near field communication is made possible between the information processing device and a storage device, the determination unit determines whether or not the storage device is a permitted storage device, an access to which by an application program to be executed by the information processing device is permitted. Under the condition that the storage device with which the near field communication is made possible for the information processing device is a permitted storage device, the permission unit permits the shared data to be used in the application program to be executed by the information processing device.

(12)

The first processing unit may execute a process of displaying the object on a display device as the first process. The second processing unit may execute, as the second process, a process of displaying the object on the display device, the process being different from the first process.

(13)

The second processing unit may execute, as the second process, a process of displaying the object in a different display manner from the display manner in which the object is displayed in the first process.

(14)

When executing a game application program different from the predetermined application program, the second processing unit may execute, as the second process, a process that does not influence progress of the game.

(15)

The storage device may have an external appearance representing, three-dimensionally or two-dimensionally, an object represented by the shared data.

(16)

The storage device may store a hash value on a part of, or the entirety of, the data stored thereon. The determination unit may determine whether or not the storage device is a permitted storage device based on a hash value calculated from data read from the storage device and the hash value read from the storage device.

(17)

Still another example of information processing system described in this specification is an information processing system including a storage device; and an information processing device for performing near field communication with the storage device.

The storage device has an external appearance representing, three-dimensionally or two-dimensionally, an object that appears in a virtual space generated by execution of a predetermined application program by the information processing device. The storage device stores first identification information on the object and second identification information on a group to which the object belongs.

The information processing device executes a predetermined process by use of the first identification information read from the storage device and executes the predetermined process by use of the second identification information read from the storage device.

(18)

The information processing device may include a first determination unit, a second determination unit, and a processing execution unit. The first determination unit determines, while executing an application program, whether or not the first identification information read from the storage device represents a value registered in the application program that is being executed. The second determination unit determines whether or not the second identification information read from the storage device represents a value registered in the application program that is being executed. In the case where at least one of the first identification information and the second identification information read from the storage device represents a value registered in the application program that is being executed, the processing execution unit executes the predetermined process in the application program.

(19)

The predetermined process may be a process on the object.

In the case where the first identification information read from the storage device represents a value registered in the application program that is being executed, the processing execution means may specify the object by use of the first identification information. In the case where the first identification information read from the storage device does not represent a value registered in the application program that is being executed and the second identification information read from the storage device represents a value registered in the application program that is being executed, the processing execution means may specify the object by use of the second identification information.

This specification discloses an example of the information processing device or storage device included in the information processing system according to (1) through (19), and also disclose an example of non-transitory computer-readable storage medium storing an information processing program which causes a computer of the information processing device to function as each of units of the information processing device. This specification discloses an example of information processing method executable by the information processing system.

According to an information processing system, an information processing device, a storage medium storing an information processing program, an information processing method and a storage device described above, the storage device performing near field communication can be used in a more versatile manner.

These and other objects, features, aspects and advantages will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS 1. Structure of the Information System

Hereinafter, an information processing system, an information processing device, a storage medium storing an information processing program, an information processing method, and a storage device according to an example of the example embodiment will be described. First, a structure of an information processing system will be described. FIG. 1 shows a structure of an example of information processing system in the example embodiment. As shown in FIG. 1, an information processing system 1 includes a storage device (tag) 2 and an information processing device 3. The information processing device 3 is an optional information processing device capable of performing near field communication with the tag 2.

In the example embodiment, a case in which communication based on the NFC standards is performed between the information processing device 3 and the tag 2 will be described as an example of near field communication. Herein, “near field communication” refers to a communication system by which radio waves (e.g., electromagnetic induction) from one device generates an electromotive force in the other device. The other device is operable by the generated electromagnetic force (the other device may or may not have a power source). In the near field communication, the information processing device 3 and the tag 2 become communicable with each other when approaching each other (typically, when the distance therebetween becomes several ten centimeters or shorter). In the near field communication, radio waves are kept transmitted while the communication between two communication devices are established (i.e., while one of the communication devices (tag) is close to the other communication device).

The information processing device 3 is an optional information processing device capable of performing near field communication. In the example embodiment, the information processing device 3 may be, for example, a mobile (also referred to as “portable”) device such as a mobile game device, a mobile phone, a smart phone or the like; an installation type device such as a personal computer, a home-use game device or the like; or a large-scale device such as a commercial-use arcade game device or the like. For example, the information processing device 3 is a mobile device having an NFC reader/writer function.

The tag 2 is an optional device capable of performing near field communication with the information processing device 3. In the example embodiment, the tag 2 is a storage device having an NFC tag function. Namely, the tag 2 includes a circuit (IC chip) for performing near field communication and a storage unit (memory, etc.) storing data. The tag 2 is not limited to a device having only a function of storing data, and may be an information processing device (mobile device) having an NFC card emulation function.

Hereinafter, a structure of the information processing device 3 will be described. As shown in FIG. 1, the information processing device 3 includes a communication unit 11. The communication unit 11 is an antenna usable for near field communication. The information processing device 3 also includes a communication chip 12. The communication chip 12 generates a signal (radio wave) to be transmitted from the communication unit 11 in conformity to an instruction from a CPU 13 (described later). The generated signal is transmitted from the communication unit 11. The communication chip 12 is, for example, an NFC chip.

As shown in FIG. 1, the information processing device 3 includes the CPU 13 and a memory 14. The CPU 13 is an information processing unit for executing various types of information processes to be executed by the information processing device 3. The CPU 13 executes the above-described various types of information processes by use of the memory 14.

The information processing device 3 includes a program storage unit 15. The program storage unit 15 stores various programs (including a communication program and an application program described later) to be executed by the information processing device 3. The program storage device 15 is an optional storage device (storage medium) accessible by the CPU 13. The program storage unit 15 may be a storage unit built in the information processing device 3 such as, for example, a hard disc or a memory; a storage medium detachable from the information processing device 3 such as, for example, an optical disc or a cartridge; or both of such a storage unit and such a storage medium.

In the example embodiment, in the information processing device 3, at least two types of programs, namely, an application program and a communication program, are stored on the storage unit 15. The application program is a program for executing an optional application of performing data communication with the tag 2. The application program may be, for example, a game program of reading game data from the tag 2 and performing a game process by use of the game data. The communication program is a program for performing near field communication with the tag 2. The communication program may be, for example, firmware for causing the communication chip 12 to operate, and may be prepared in the information processing process 3 as a library in advance. As described later in detail, the communication program receives an instruction from the application and causes the communication chip 12 to perform an operation for communication. In the case where the information processing device 3 is capable of executing a plurality of application programs, the communication program is shared by the plurality of applications. Namely, the communication program (communication control unit 32 described later) can accept an instruction on communication from a plurality of applications.

The information processing device 3 also includes an input unit 16 for accepting an instruction from a user such as a button, a touch panel or the like. The information processing device 3 further includes a display unit 17 for displaying an image generated by an information process as described above.

The information processing device 3 may include a plurality of devices. For example, the information processing device 3 may include a device including the CPU 13 and the memory 14 and a device including the communication unit 11 and the communication chip 12, and the latter device may be detachably connected to the former device. The information processing device 3 may include a main body device including the CPU 13 and a separate device including the input unit 16 and/or the display unit 17. For example, in another embodiment, the information processing device 3 may include a main body device and a terminal device including the input unit 16 and the display unit 17. Alternatively, the information processing device may include a main body device and an operation device including the input unit 16. Still alternatively, the information processing device 3 may not include the display unit 17 and may use a TV as a display device.

In another embodiment, at least a part of the information process to be executed by the information processing device 3 may be executed in a distributed manner by a plurality of devices communicable with each other via a network (wide area network and/or local area network).

FIG. 2 shows an example of external appearance of the tag 2. As shown in FIG. 2, the tag 2 in the example embodiment is a figure-type tag having an external appearance representing a character. The character represented by the tag 2 is a character appearing in a specific application (e.g., game) executable by the information processing device 3. A user can use the tag 2 to cause the character to appear in the specific application. Namely, when executing the program of the specific application, the information processing device 3 uses the data stored on the tag 2 to cause the above-described character to appear in a virtual space generated by the program of the specific application. The figure-type tag 2 represents an optional object appearing in the application. The figure-type tag 2 is not limited to representing a character, and may represent an item in the game application.

As described above, the tag 2 is used in a specific application program. As described later in detail, the tag 2 can store data usable only in a specific application program (dedicated data described later). Hereinafter, such a specific application program will be referred to as a “specific application program”. There may be one type of specific application program or a plurality of types of specific application programs corresponding to one type of tag. In the case where, for example, a plurality of types of applications are provided for one series, the plurality of types of applications may be specific application programs.

As described later in detail, the tag 2 is usable in a specific application program and also is usable in another application program. Namely, the tag 2 stores data usable only in a specific application program and also store data usable in another application program. Hereinafter, an example of data stored on the tag 2 will be described.

FIG. 3 shows an example of data stored on the tag 2. In the example embodiment, as shown in FIG. 3, the tag 2 includes a read-only area 21 and a read/write area 22. The read-only area 21 is a storage area that only allows data stored thereon to be read. The read/write area 22 is a storage area that allows data stored thereon to be read and also allows data to be written thereto. Data is stored in the read-only area 21 during the production of the tag 2, and after that (after the tag 2 is shipped), data write to the read-only area 21 is prohibited. Namely, the information processing device 3 (application program to be executed by the information processing device 3) cannot write data to the read-only area 21. By contrast, the information processing device 3 (application program to be executed by the information processing device 3) can read and write from and to the read/write area 22. At the time of shipping of the tag 2, data may or may not be stored in the read/write area 22. In either case, when the tag 2 and the information processing device 3 communicate with each other, data is written to the read/write area 22 by the information processing device 3 and stored therein.

In the example embodiment, roughly three types of data, namely, dedicated data, shared data and management data, are stored on the tag 2. As shown in FIG. 3, in the example embodiment, storage areas in which respective types of data are stored (dedicated data area, shared data area and management data area) are predefined. In another embodiment, such storage areas may not be predefined.

The dedicated data is data usable only in a specific application program as described above. In the example embodiment, the dedicated data includes saved data of the specific application program (see FIG. 3). Data stored as saved data includes, for example, data representing a parameter on the character represented by the tag 2, data representing how the game of the specific application program is progressing, and/or data on a player of the game of the specific application program. In the example embodiment, the dedicated data is stored in the read/write area 22 and is not stored in the read-only area 21 (see FIG. 3).

Now, the shared data will be described. The shared data is data usable in a specific application program and also an application program that is not a specific application program. In the example embodiment, the shared data is stored in both of the read-only area 21 ands the read/write area 22. The tag 2 may store the shared data in only either one of the read-only area 21 ands the read/write area 22.

On the read-only area 21, at least the following data (information) is stored as the shared data.

Individual ID (data representing the individual ID)

Type ID (data representing the type ID)

Figure ID (data representing the figure ID)

Series ID (data representing the series ID)

Use ID (data representing the use ID)

The individual ID is identification information specific to the tag. An NFC tag such as the tag 2 in the example embodiment stores identification information specific to the tag that is called a UID (Unique ID). The individual ID is different from the UID. The individual ID is an ID that is different from the UID and is assigned so that a provider of a service using the tag can manage the tag easily.

The figure ID is identification information specific to the external appearance (shape, color) of the figure-type tag 2. The figure ID is identification information that allows the type of the figure of the tag 2 to be uniquely specified. In the case where, for example, there are a plurality of tags having different external appearances (e.g., different poses or clothes) for one character, each tag is assigned a figure ID of a different value. In this case, the figure ID may include an ID specific to the character and also an ID representing a pose, clothes or the like of the corresponding tag.

An application program executable by the information processing device 3 includes a figure ID of a tag to be used (usable) by the application program itself. As described later in detail, in the case where the value of the figure ID included in the application program matches the value of the figure ID stored on the tag, the application program can use the dedicated data stored on the tag. Namely, the figure ID can be considered as identification information for managing the use of the dedicated data stored on the tag 2.

The series ID is identification information specific to a group to which the object (character) represented by the tag 2 belongs. In the case where, for example, the character represented by the tag 2 appears in a plurality of types of applications (e.g., a series of game applications), the plurality of types of applications may be set as one group, and a series ID representing the group may be set.

The type ID is identification information that represents the type of the tag 2. In the example embodiment, the information processing device 3 can use a card-type tag as well as a figure-type tag such as the tag 2. The tag ID is identification information that represents whether the tag is a figure-type tag or a card-type tag. In another embodiment, the type of tag identified by the type ID is optional. For example, each of tag providers may be assigned a different type ID.

The use ID is identification information that specifies an application program that can use the dedicated data (described later in detail) stored on the tag 2 (i.e., specifies the above-described specific application program). Herein, an application program executable by the information processing device 3 is assigned a use ID. In the example embodiment, the figure ID is used to manage the use of the dedicated data stored on the tag 2 (see a specific application/non-specific application determination process described later). In another embodiment, a use ID may be used to manage the use of the dedicated data stored on the tag 2.

As shown in FIG. 3, in the read/write data 22, initial registration data and update data are stored as the shared data. The content of the shared data stored on the tag 2 is optional. For example, in another embodiment, the tag 2 may store only either one of the initial registration data and the update data as the shared data.

The initial registration data is data registered by the user at the start of the use of the tag 2 by the information processing device 3. The initial registration data is typically stored on the tag 2 at the timing when the tag 2 is first used, but may be stored on the tag 2 at an optional timing. Namely, the user 2 may register the tag 2 at an optional timing.

In the example embodiment, the initial registration data includes the following data.

Avatar data

Nickname (data representing the nickname)

Registration date/time (data representing the registration date/time)

Region (data representing the region)

The avatar data is data on an avatar of the user. The avatar data includes data usable by the information processing device 3 to generate an avatar and display the avatar on the display unit 17. Specifically, the avatar data includes data representing each of sites of the avatar (shapes of the eye, nose and the like, body shape, etc.). In the example embodiment, the information processing device 3 stores a program for generating an avatar by use of the avatar data. In the example embodiment, the program for generating an avatar is stored in advance as a system program or a library of the information processing device 3. The avatar can be displayed in each of the application programs (by use of the avatar generation program).

The nickname is a nickname given to the tag 2 by the user. In the case where, for example, one user possesses two or more tags having the same external appearance, the user can give different nicknames to the tags so as to distinguish the tags.

As described later in detail, at the time when an initial registration process is executed on the tag (see FIG. 7 and FIG. 8 described later), the information processing device 3 causes the user to input the avatar data and the nickname. The input data and data on the registration date/time and on the region (described later) are stored on the tag 2 as the initial registration data.

The registration date/time is the date/time when the initial registration is performed. The region is the region where the initial registration is performed. As described later in detail, in the example embodiment, the data on the registration date/time and on the region is automatically written to the tag 2 by the information processing device 3 in the initial registration process.

Now, information included in the update data will be described. The update data is data that is updated when the tag 2 and the information processing device 3 communicate with each other (under a certain condition). In the example embodiment, the update data includes the following data.

Number of times of write (data representing the number of times of write)

Last-write device (data representing the last-write device)

Number of times of device change (data representing the number of times of device change)

Last-used application (data representing the last-used application)

Last-write date/time (data representing the last-write date/time)

As described later in detail, in the example embodiment, the update data stored on the tag 2 is updated (overwritten) at the timing when the dedicated data is written.

The number of times of write is the number of times the dedicated data has been written on the tag 2.

The last-write device is the information processing device that wrote the dedicated data to the tag 2 most recently. In the example embodiment, each of a plurality of information processing devices is assigned identification information specific thereto. Data on a hash value on the identification information on the information processing device that wrote data is stored as the data on the last-write device (alternatively, data on the identification information itself that wrote data may be stored).

The number of times of device change is the number of times the information processing device that wrote the dedicated data was changed. As described later in detail, in the case where, for example, an information processing device possessed by the user writes data to the tag 2 and then an information processing device different from the information processing device possessed by the user (e.g., an information processing device installed in a store the user visits or an information processing device possessed by a friend of the user) writes data to the tag 2, the number of times of device change is updated.

The last-used application is the application program that wrote the dedicated data to the tag 2 most recently. In the example embodiment, the data stored as the data on the last-used application is not the use ID but the identification information specific to the application program.

The last-write date/time is the date/time when the dedicated data was written to the tag 2 most recently.

Now, the management data will be described. The management data is data used for management of the tag, and is used in, for example, an access permission/non-permission determination process or the like. Basically, the management data is not used in an application.

As shown in FIG. 3, the tag 2 stores data on version information in the read-only area 21 as the management data. The version information represents a version of a data format (storage format) of the tag 2. In the example embodiment, the data storage format of the data on the tag 2 varies on a version-by-version basis and that the same version has the same data storage format. Specifically, in the example embodiment, which data is stored at which address of the tag 2 is defined on a version-by-version basis (it should be noted that the address at which the data on the version information is stored is the same among different versions). Therefore, the information processing device 3 can specify the address at which each piece of data is stored by referring to the version information. For example, a data size of each piece of data (size of a storage area of each piece of data) may be defined by the version information, so that an address can be specified based on the version information.

The tag 2 stores a first hash value and a second hash value as the management data (see FIG. 3). The first hash value corresponds to the data in the read-only area 21. The second hash value corresponds to the data in the read/write area 22. The hash values are obtained by applying a predetermined algorithm (hash function) to the corresponding data. The contents of the data in the read-only area 21 are not changed, and the first hash value is not changed. Therefore, in the example embodiment, the data on the first hash value is stored in the read-only area 21. When the contents of the data in the read/write area 22 are changed, the second hash value is changed. Therefore, the data on the second hash value is stored in the read/write area 22.

In the example embodiment, the dedicated data and the shared data, among the data shown in FIG. 3, are encrypted by a method which allows the encrypted data to be decrypted by the information processing device 3 (in the example embodiment, the communication control unit 32 described later). The dedicated data and the shared data may be encrypted by the same method or different methods. Because of the encryption, even if the data is read from the tag 2 by a device that does not have a decryption function of the above-described method, such a device cannot decipher the contents of the data. This can improve the security of the data stored on the tag 2. In another embodiment, the management data may also be encrypted, or at least one of the three types of data does not need to be encrypted.

2. Processing Operations of the Information Processing System

Now, with reference to FIG. 4 through FIG. 12, processing operations of the information processing system 1 regarding data read and write from and to the tag 2 will be described. As shown in FIG. 4 and the like, in the example embodiment, the operations of the information processing device 3 will be described as being divided by function into the operations of an application unit 31 and operations of the communication control unit 32. In the example embodiment, the application unit 31 is the CPU 13 for executing an application program as described above. The communication control unit 32 is realized by the CPU 13 for executing a communication program as described above, the communication chip 12 and the communication unit 11. In another embodiment, the information process performed by the information processing device 3 does not need to be realized by two types of programs, namely, the application program and the communication program, and may be realized by a single program.

Hereinafter, with reference to FIG. 4 through FIG. 6, an operation of reading data from the tag 2 will be described. FIG. 4 and FIG. 5 each show an example of flow of a process executed by the information processing system 1 for reading data from the tag 2 by a specific application program. FIG. 4 shows a flow in the case where a specific application program is executed by the information processing device 3, namely, in the case where the application unit 31 is realized by the CPU 13 that executes the specific application program. FIG. 5 shows a flow in the case where another application program that is not the specific application program is executed by the information processing device 3, namely, in the case where the application unit 31 is realized by the CPU 13 that executes the another application program.

FIG. 6 is a flowchart showing an example of flow of a process executed by the communication control unit 32 that has accepted a read instruction (i.e., showing a read instruction process). The process in each of steps in the flowchart shown in FIG. 6 (also the flowcharts in FIG. 8, FIG. 10 and FIG. 12 described later) is merely exemplary. As long as substantially the same results are obtained, the order of the processes of the steps may be changed, or another process may be executed in addition to (or instead of) the process of each step. In the example embodiment, the process of each step in the flowcharts will be described as being executed by the CPU 13. Alternatively, the process of a part of the steps in the flowcharts may be executed by a processor other than the CPU 13 or by a dedicated circuit.

First, the application unit 31 transmits a read instruction, which is to read data from the tag 2, to the communication control unit 32 (see FIG. 4 and FIG. 5). In the example embodiment, the read instruction includes the figure ID. As described above, the specific application program includes information on the figure ID of the tag storing the dedicated data usable in the specific application program itself. Therefore, the application unit 31 transmits the figure ID included in the specific application program together with the read instruction to the communication control unit 32.

The application program 31 transmits all the figure IDs included in the specific application program. In the case where the type of the tag can be specified, the application program 31 may transmit, to the communication control unit 32, only the figure ID of the tag among one or more figure IDs included in the specific application program. For example, in the case where in a game situation of using a tag representing a character operated by a player, data on the tag is to be read, the tag 2 connected to the information processing device 3 can be specified as the tag representing the character. Therefore, in this case, the application unit 31 may transmit only the figure ID of the tag 2 representing the character to the communication control unit 32.

In another embodiment, the application unit 31 may transmit the figure ID to the communication control unit 32 at a different timing from the timing when the read instruction is transmitted (this is applicable to other instructions including a write instruction). For example, in another embodiment, the communication control unit 32 may request the application unit 31 to transmit the figure ID in a specific application/non-specific application determination process described later, and the application unit 31 may transmit the figure ID to the communication control unit 32 in response to the request.

Upon acceptance of the read instruction, the communication control unit 32 starts execution of a series of processes of steps S1 through S7 shown in FIG. 4 through FIG. 6 (read instruction process). First, in step S1, the communication control unit 32 executes a connection process in order to start communication with the tag 2. The specific content of the connection process is optional. For example, the communication control unit 32 executes a process of detecting the tag 2 present in the vicinity of the communication unit 11 (e.g., polling process) and a process of establishing communication with the detected tag 2 (e.g., process of acquiring information to be used for data communication from the tag 2). Although not shown, in the case where the tag 2 is distanced from the information processing device 3 and it is made impossible to perform near field communication during the read instruction process (also in a registration instruction process or the write instruction process described later), the communication control unit 32 terminates the read instruction process and discontinues data transfer with the application unit 31.

In step S2, the communication control unit 32 executes a data read process. Specifically, the communication control unit 32 first reads the management data from the tag 2. Based on the version information included in the read management data, the communication control unit 32 specifies the address of each piece of data (data included in the dedicated data and the shared data) in the tag 2. The method for specifying the address based on the version information may be optional. For example, the version information itself may include information that represents the correspondence between each piece of data and the address. Alternatively, the communication control unit 32 may store a table associating the correspondence and the version information in advance, so that the communication control unit 32 can specify the correspondence by use of the version information read from the tag 2 and the table.

Once the address of each piece of data included in the dedicated data and the shared data is specified, the communication control unit 32 reads the shared data and the dedicated data from the tag 2. The communication control unit 32 decrypts and stores the read data on the memory 14. In this manner, in the example embodiment, the communication control unit 32 reads the shared data and the dedicated data from the tag 2 regardless of the content of the read instruction from the application unit 31 (which of the data stored on the tag 2 is to be read) and the type of the application program (whether or not the application program is the specific application program).

In step S3, the communication control unit 32 executes the access permission/non-permission determination process. The access permission/non-permission determination process is a process of determining whether or not an access by the application program to be executed by the information processing device 3 to the tag with which the communication has been established is permissible. In other words, the access permission/non-permission determination process is a process of determining whether or not the tag with which the communication has been established is a permitted tag. The “permitted tag” refers to a tag, an access to which by the application program to be executed by the information processing device 3 is permitted. The permitted tag is, for example, a tag permitted by a provider of the information processing device 3 (and/or of the application program executable by the information processing device 3). Namely, in the example embodiment, the application program on the information processing device 3 can access only the tag permitted by the provider, and cannot read/write data from/to an NFC tag that is not permitted by the provider.

In the example embodiment, the determination in the access permission/non-permission determination process is made by use of the hash values on the data stored on the tag 2 (first hash value and second hash value). Specifically, the communication control unit 32 calculates a hash value (first hash value) on the data that has been read in step S2 from the read-only area 21 by use of the predetermined algorithm. The communication control unit 32 determines whether or not the calculated hash value matches the first hash value read in step S2. In the case where these two hash values match each other, the communication control unit 32 makes a similar determination on the data that has been read from the read/write area 22 and the second hash value. Namely, the communication control unit 32 calculates a hash value (second hash value) on the data that has been read in step S2 from the read/write area 22 by use of the predetermined algorithm, and determines whether or not the calculated hash value matches the second hash value read in step S2.

In the case where the calculated hash value matches the read second hash value, the communication control unit 32 determines that the tag 2 is a permitted tag. In this case, the communication control unit 32 executes a process of step S5. By contrast, in the case where the hash values do not match each other in one of the determinations, the communication control unit 32 determines that the tag 2 is not a permitted tag. In this case, the communication control unit 32 executes a process of step S4.

As described above, in the example embodiment, the tag 2 stores the hash values (first hash value and second hash value) on a part of, or the entirety of, the data stored thereon. The communication control unit 32 determines whether or not the tag 2 is a permitted tag based on the hash value calculated based on the data read from the tag 2 and the hash value read from the tag 2. The hash values are stored on the tag 2 as described above, so that the determination on whether or not the tag 2 is a permitted tag can be made easily.

In another embodiment, the determination in the access permission/non-permission determination process may be made by another method. For example, the communication control unit 32 may store, in advance, predetermined information stored on the tag 2 (also on the side of the information processing device 3) and make the determination based on whether or not the information read from the tag matches the information stored in advance. The predetermined information usable for the determination may be, for example, the following information.

Information that is stored on an NFC tag and represents the type of the tag defined by the NFC standards (Type 1, Type 2, etc.)

Information (exclusive code) that represents that the tag 2 is a tag permitted by the provider of the information processing device 3 (and/or of the application program executable by the information processing device 3)

Version information as described above

Alternatively, for example, the determination in the access permission/non-permission determination process may be made based on whether or not the data stored in the read-only area 21 is adapted to the setting specified by the version information. Still alternatively, for example, the determination in the access permission/non-permission determination process may be made based on whether or not the size of the predetermined data read by the communication control unit 32 (e.g., data stored in the read-only area 21) is within a predetermined range.

In step S4, the communication control unit 32 notifies the application unit 31 that the tag 2 is not a permitted tag. Upon receipt of this notification, the application unit 31 may perform an optional process. For example, the application unit 31 notifies the user that the tag 2 is not a permitted tag and therefore data cannot be read. After the process of step S4, the communication control unit 32 terminates the read instruction process shown in FIG. 6.

In step S5, the communication control unit 32 executes a specific application/non-specific application determination process. The specific application/non-specific application determination process is a process of determining whether or not the application program that issued the instruction to the communication control unit 32 (herein, the read instruction) is a specific application program.

The determination in the specific application/non-specific application determination process is made by use of the figure ID. Namely, the communication control unit 32 compares the figure ID acquired from the application unit 31 together with the instruction (in the case where there a plurality of figure IDs, one of the figure IDs) against the figure ID read from the tag 2 in step S2. In the case where the figure IDs match each other, the communication control unit 32 determines that the application program that issued the instruction is a specific application program. In this case, the communication control unit 32 executes a process of step S6. By contrast, in the case where the figure IDs do not match each other, the communication control unit 32 determines that the application program that issued the instruction is a non-specific application program (application program that is not a specific application program). In this case, the communication control unit 32 executes a process of step S7.

In step S6, the communication control unit 32 transfers (outputs) the dedicated data and the shared data to the application unit 31 (see FIG. 4). Namely, in the case where the application program that issued the instruction is a specific application program, the communication control unit 32 permits the application unit 31 to receive the dedicated data. After the process of step S6 is finished, the communication control unit 32 terminates the read instruction process shown in FIG. 6.

Upon receipt of the dedicated data and the shared data from the communication control unit 32, the application unit 31 executes an information process by use of the received data. The content of the information process is optional. For example, the application unit 31 executes a game process by use of the saved data, which is the dedicated data. In the example embodiment, the specific application program uses the saved data, which is the dedicated data. Alternatively, the specific application program may use the shared data in addition to (or instead of) the dedicated data.

In step S7, the communication control unit 32 transfers (outputs) the shared data to the application unit 31 (see FIG. 5). Namely, in the case where the application program that issued the instruction is a non-specific application program, the communication control unit 32 restricts (prohibits) the application unit 31 from receiving the dedicated data. After the process of step S7 is finished, the communication control unit 32 terminates the read instruction process shown in FIG. 6.

Upon receipt of the shared data from the communication control unit 32, the application unit 31 executes an information process by use of the received data. The content of the information process is optional. For example, the application unit 31 may execute the following processes.

Process of using the figure ID to display a character represented by the figure ID (see FIG. 12)

Process of using the avatar data to display an avatar of the user (e.g., process of executing a game using the avatar as a player character)

Process of storing the nickname on the information processing device 3 and displaying the nickname at an appropriate timing

Process in accordance with the content of the update data (e.g., process of providing a benefit for the game in the case where the number of times of write is equal to or greater than a predetermined number of times; process of displaying the message “long time no see” in the case where the last-write date/time is before a predetermined time; etc.)

In the example embodiment, in the data output process of step S6 or S7, the communication control unit 32 outputs all of the shared data (and the dedicated data) stored on the tag 2 to the application unit 31. In another embodiment, the application unit 31 may specify, in the read instruction, the data to be acquired, and output the data specified in the read instruction to the application unit 31 in the process of S6 of S7. In the case where the data specified in the read instruction is the dedicated data and it is determined in step S4 that the application program that issued the read instruction is a non-specific application program, the communication control unit 32 may notify the application unit 31 in step S7 that the data output (read) is restricted.

(2-2: Operation for Initial Registration)

Now, with reference to FIG. 7 and FIG. 8, an operation of writing the initial registration data to the tag 2 will be described. FIG. 7 shows an example of flow of a process executed by the information processing system 1 for writing the initial registration data to the tag 2. FIG. 8 is a flowchart showing an example of flow of a process executed by the communication control unit 32 that has accepted a registration instruction (i.e., showing a registration instruction process).

First, the application unit 31 outputs a registration instruction to the communication control unit 32, and the communication control unit 32 accepts the registration instruction. The registration instruction is an instruction to write the initial registration data to the tag 2. In the example embodiment, the application unit 31 issuing the registration instruction is realized by a system application program (OS program) in the information processing device 3. Namely, the initial registration data is written by the system application program (as a function of the information processing device 3). For example, an instruction to make an initial registration to the tag 2 is issued by the user while the system application program is executed (e.g., while a menu screen is displayed). In response to this instruction being accepted, the application unit 31 outputs the registration instruction.

In the example embodiment, only the system application can write the shared data. In another embodiment, another application (specific application and/or non-specific application) can write the shared data.

Upon acceptance of the registration instruction, the communication control unit 32 starts execution of a series of processes of steps S1 through S3 and steps S11 through S13 shown in FIG. 7 and FIG. 8 (registration instruction process). The processes in steps S1 through S3 shown in FIG. 8 are the same as those shown in FIG. 6.

In the registration instruction process, in the case where the determination result in step S3 is positive (in the case where the tag 2 is a permitted tag), a process of step S11 is executed. By contrast, in the case where the determination result in step S3 is negative (in the case where the tag 2 is not a permitted tag), a process of step S4 shown in FIG. 6 is executed.

In the registration instruction process, upon receipt of the notification that the tag 2 is not a permitted tag as a result of the process of FIG. 4, the application unit 31, for example, notifies the user that the tag 2 is not a permitted tag and therefore data cannot be registered. After the process of step S4, the communication control unit 32 terminates the registration instruction process shown in FIG. 8

By contrast, in step S11, the communication control unit 32 outputs a notification that the tag 2 is a permitted tag (permission notification) to the application unit 31. FIG. 7 shows a process executed in the case where the permission notification is output to the application unit 31.

Upon receipt of the permission notification, the application unit 31 acquires the initial registration data to be written to the tag 2 (step S21 shown in FIG. 7). In the example embodiment, the application unit 31 accepts the avatar data and data on the nickname from the user, and also acquires the data on the registration date/time and on the region. Specifically, the application unit 31 prepares in advance a plurality of candidates of each site of the avatar (eyes, nose, etc.) and causes the user to choose a desirable shape from the candidates. In this manner, the avatar data conformed to the instruction of the user can be acquired. The application unit 31 causes the user to input desired letter information, so that the nickname can be acquired. Data representing the current date/time and data representing the region (country) where the information processing device 3 exists are stored on the information processing device 3, so that the application unit 31 acquires these types of data. The application unit 31 transfers (outputs) the initial registration data thus acquired to the communication control unit 32.

In step S12, the communication control unit 32 acquires the initial registration data from the application data 31. In another embodiment, the communication control unit 32 may acquire data specified by the user (avatar data and data on the nickname) from the application unit 31 and acquire the data stored on the information processing device 3 (data on the current date/time and on the region) by the communication control unit 32 itself.

In step S13, the communication control unit 32 executes a write process to the tag 2. In the example embodiment, the entirety of the data to be stored in the read/write area 22 is written to the tag 2 as one unit. Namely, the communication control unit 32 writes the dedicated data read in step S2, new shared data which includes the shared data read in step S2 and the initial registration data, and the data on the second hash value to the tag 2. As the shared data excluding the initial registration data, the data read and stored on the memory 14 in step S2 is used. The addition of the initial registration data changes the contents of the shared data. Therefore, in step S13, the communication control unit 32 calculates a hash value on the post-change shared data (shared data including the initial registration data), and writes the calculated hash value to the tag 2 as a new second hash value. After the process of step S13, the communication control unit 32 terminates the registration instruction process.

The above description is provided with an assumption that the initial registration data is not stored on the tag 2. In the case where the initial registration data is stored on the tag 2 also, substantially the same registration instruction process as described above can be executed to update the contents of the initial registration data. In this case, in step S13, the communication control unit 32 writes the dedicated data read in step S2, and new shared data obtained as a result of the initial registration data included in the shared data read in step 2 being updated, to the tag 2. As described above, the application unit 31 may transmit the registration instruction to the application unit 31 in order to update the initial registration data already registered on the tag 2 as well as in order to newly write the initial registration data to the tag 2.

In another embodiment, the communication control unit 32 may execute the process of writing the initial registration data at the time of performing the near field communication with the tag in response to the read instruction or the write instruction. In the case where, for example, data is read from the tag 2 in step S2 in the read instruction process, the communication control unit 32 may determine whether or not the initial registration data is stored on the tag 2, and in the case where the initial registration data is not stored on the tag 2, the communication control unit 32 may make a notification to the application unit 31. In response to this notification, the application unit 31 may execute the process of step S21 and the communication control unit 32 may execute the processes of steps S12 and S13. In this manner, the communication control unit 32 can write the initial registration data to the tag 2 in the read instruction process (in the case where the initial registration data has not been registered).

(2-3: Operation of Writing Data)

Now, with reference to FIG. 9 and FIG. 10, an operation of writing the dedicated data (and the update data) to the tag 2 will be described. FIG. 9 shows an example of flow of a process executed by the information processing system 1 for writing the dedicated data to the tag 2. FIG. 10 is a flowchart showing an example of flow of a process executed by the communication control unit 32 that has received a write instruction (i.e., showing a write instruction process).

First, the application unit 31 transmits a write instruction, which is to write data to the tag 2, to the communication control unit 32 (see FIG. 9 and FIG. 10). The write instruction includes the figure ID included in the application program in the application unit 31, like the read instruction described above.

Upon acceptance of the write instruction, the communication control unit 32 starts execution of a series of processes shown in FIG. 10 (write instruction process). The processes of steps S1 through S6 in the write instruction process are substantially the same as those in the read instruction process described above. As can be seen, in the example embodiment, data is read from the tag 2 before data is written to the tag 2. As described later in detail, the read data is appropriately changed, and the post-change data is written to the tag 2.

In the write instruction process, in the case where the determination result in step S5 is negative (in the case where the application program that issued the write instruction is not a specific application program), a process of step S31 is executed. In step S31, the communication control unit 32 notifies the application unit 31 that the data cannot be written. Upon receipt of this notification, the application unit 31 executes an optional process. For example, the application unit 31 executes a process of notifying the user that the connected tag 2 is a not tag to which the application program that is being executed can write data. After the process of step S31, the communication control unit 32 terminates the write instruction process.

By contrast, in the case where the determination result in step S5 is positive (in the case where the application program that issued the write instruction is a specific application program), a process of step S6 is executed. Namely, the communication control unit 32 transfers (outputs) the dedicated data and the shared data to the application unit 31 (see FIG. 9 and FIG. 10). As described above, the data to be transferred to the application unit 31 in step S6 is not limited to the dedicated data and the shared data. For example, only the dedicated data (saved data) may be transferred. In the write instruction process, the communication control unit 32 may execute a process of notifying the application unit 31 that the data write is permitted instead of the process of step S6.

Upon receipt of the dedicated data and the shared data, the application unit 31 transfers the data to be written to the tag 2 (herein, saved data) to the communication control unit 32. Namely, in step S32, the communication control unit 32 acquires the data to be written to the tag 2 from the application unit 31.

In step S33, the communication control unit 32 generates update data to be written to the tag 2. As described above, in the example embodiment, the update data is updated at the time when the dedicated data (saved data) is written to the tag 2. Therefore, the communication control unit 32 acquires (generates) data on the number of times of write, the last-write device, the number of times of device change, the last-used application, and the last-write date/time. Specifically, as the data on the number of times of write, the communication control unit 32 generates data representing a value that is obtained as a result of 1 being added to the number of times of write represented by the update data read in step S2. As the data on the last-write device, the communication control unit 32 acquires data on the identification information on the information processing device 3, which is stored on the information processing device 3 itself (e.g., on the memory 14). As the data on the last-used application, the communication control unit 32 acquires the data on the identification information on the application program that issued the write instruction (application ID) from this application program. As the data on the last-write date/time, the communication control unit 32 acquires the current date/time. The data on the number of times of device change is calculated as follows.

FIG. 11 shows an example of method for counting the number of times of device change. FIG. 11 shows a case where the user first writes data (saved data) to the tag 2 by use of an information processing device 3 a possessed by the user at home. It is assumed that the number of times of device change N at this point is “A”. Even if the user writes saved data to the tag 2 by use of the information processing device 3 a after this, the number of times of device change N remains “A”.

As shown in FIG. 11, after the saved data is written to the tag 2 by the information processing device 3 a, the user (moves with the tag 2 and) writes saved data to the tag 2 by use of another information processing device 3 b. The another information processing device 3 b is, for example, an information processing device possessed by a friend of the user, or an information processing device installed in a store for the purpose of sales promotion or the like. At the time when the saved data is written to the tag 2 by the another information processing device 3 b, the number of times of device change N is updated to “A+1”. Even if saved data is written to the tag 2 by the another information processing device 3 b after this, the number of times of device change N remains “A+1”.

As shown in FIG. 11, after this, the user (moves with the tag 2) and writes saved data to the tag 2 by use of the information processing device 3 a possessed by the user. At the time when the saved data is written to the tag 2 by the information processing device 3 a, the number of times of device change N is updated to “A+2”.

As described above, in the example embodiment, in the case where the information processing device used to write data (saved data) the immediately previously time is different from the information processing device used to write data (saved data) currently, the number of times of device change is incremented by 1. By contrast, in the case where such information processing devices are the same, the value of the number of times of device change is kept the same.

Therefore, in the process of step S33, the communication control unit 32 determines whether or not the information on the last-write device included in the shared data (update data) read in step S2 represents the information processing device 3 that issued the current write instruction. Namely, the communication control unit 32 determines whether or not the information on the last-write device included in the update data read in step S2 matches the information on the last-write device acquired in step S33 in the current cycle of operation. In the case where the information processing devices match each other, the communication control unit 32 determines that the information processing device that wrote data was not changed, and keeps the value of the number of times of device change. Namely, the communication control unit 32 sets the value of the number of times of device change read in step S2 as the value of the number of times of device change to be written to the tag 2. By contrast, in the case where the information processing devices do not match each other, the communication control unit 32 determines that the information processing device that wrote data was changed, and increments the value of the number of times of device change. Namely, the communication control unit 32 sets a value that is obtained as a result of 1 being added to the number of times of device change read in step S2 as the value of the number of times of device change to be written to the tag 2.

In the example embodiment, the update data to be updated is acquired or generated as described above.

In step S34, the communication control unit 32 executes the write process to the tag 2. As described above, in the example embodiment, the entirety of the data to be stored in the read/write area 22 is written to the tag 2 as one unit. Namely, the communication control unit 32 writes the new dedicated data acquired from the application unit 31 in step S32, and the shared data including the new update data acquired in step S33 to the tag 2. As the shared data excluding the update data, the data read and stored on the memory 14 in step S2 is used. The change of the update data changes the contents of the shared data. Therefore, in step S34, the communication control unit 32 calculates a hash value on the post-change shared data (shared data including the changed update data), and writes the calculated hash value to the tag 2 as a new second hash value. After the process of step S34, the communication control unit 32 terminates the write instruction process.

As described above, in the example embodiment, the update data is updated in the wake of the dedicated data being written to the tag 2. Alternatively, the update data may be updated at an optional timing. For example, information on the read from the tag 2 may be included in the update date (see, “4. Modification examples” described later). In this case, the update data may be updated at the timing when the data is read from the tag 2. Namely, the communication control unit 32 may execute a process of generating new update data and writing the new update data to the tag 2 after the process of step S6 or S7 in the read instruction process.

In the example embodiment, the communication control unit 32 writes the update data to the tag 2 regardless of whether or not the initial registration data is stored on the tag 2. In the example embodiment, the information processing device 3 (communication control unit 32) may write the update data to the tag 2 under the condition that the initial registration data is stored on the tag 2. In this case, the update data (e.g., number of times of write, etc.) from the time point when the initial registration is performed can be recorded.

As described above, in the example embodiment, the entirety of main data (dedicated data and shared data) as one unit is read from, or written to, the tag 2. Namely, when being read from the tag 2, the entirety of the main data is read (even when only a part of the main data needs to be read). When data is to be written to the tag 2 (when the main data on the tag 2 is to be rewritten), the entirety of the main data is rewritten (even when only a part of the main data needs to be rewritten).

In another embodiment, data write or data read to or from the tag 2 may be executed in predetermined units. For example, in the case where the storage area of the tag 2 is divided into a plurality of blocks, the data write or data read to or from the tag 2 may be executed on a block-by-block basis.

(2-4: Process by the Application Program)

Now, with reference to FIG. 12, an example of process executed by the CPU 13 (application unit 31) of the information processing device 3 in accordance with an application program will be described. FIG. 12 is a flowchart showing an example of flow of a process executed by the CPU 13 in accordance with an application program. The process shown in FIG. 12 is started in response to, for example, the user issuing an instruction to start the application.

FIG. 12 shows a game process as an example of process executed in accordance with an application program. In the example of process shown in FIG. 12, the character represented by the tag 2 is caused to appear in a game space by use of the shared data (figure ID and series ID) stored on the tag 2.

In step S41, the application unit 31 executes a game process in accordance with an application program. The contents of the game process are optional. The process that is executed is, for example, a process of controlling the operation of the character in a virtual space (game space) in response to an input of the user, or a process of controlling the operation of another character in accordance with an algorithm defined by the program.

In step S42, the application unit 31 determines whether or not to communicate with the tag 2. Namely, the application unit 31 determines whether or not a predetermined game condition for communicating with the tag 2 has been fulfilled. The predetermined game condition is that a game situation in which the character represented by the tag 2 can appear is obtained; more specifically, that a player character has advanced to a predetermined stage; that a player character has acquired a predetermined item; or the like. The process of step S42 is executed at an appropriate timing while the game process is executed in step S41. Therefore, in the case where the determination result in step S42 is negative, the process of step S41 is executed again, and the processes of steps S41 and S42 are repeated until the determination result in step S42 becomes positive. By contrast, in the case where determination result in step S42 is positive, a process of step S43 described later is executed.

In step S43, the application unit 31 outputs a read instruction and reads data from the tag 2. Namely, as described above, the application unit 31 first outputs a read instruction to the communication control unit 32 (see FIG. 4, etc.). In response to this read instruction, the communication control unit 32 communicates with the tag 2 (step S1), and transfers the data read from the tag 2 to the application unit 31 (steps S2, S6, S7). In this manner, the application unit 31 acquires the data from the tag 2. As described above, in the case where the application program that is being executed is a specific application program, the dedicated data and the shared data are acquired. In the case where the application program that is being executed is a non-specific application program, the shared data is acquired. When the data from the tag 2 is acquired in step S43, a process of step S44 is executed.

Although not shown in FIG. 12, in the case where the tag 2 that is connected to the information processing device 3 is not a permitted tag (in the case where the determination result in step S3 is negative), the communication control unit 32 notifies the application unit 31 that the tag 2 is not a permitted tag. In this case, the application unit 31, for example, notifies the user that the data cannot be read, and restarts the process of step S1.

In step S44, the application unit 31 determines whether or not the figure ID acquired in step S43 corresponds to the character registered in the application program that is being executed. The application program includes data for generating characters caused to appear in the game by the tag 2. In the application program, information on a figure ID associated with each of the characters is registered in advance. The determination in step S44 is executed based on whether or not the figure ID acquired in step S43 matches any one of the figure IDs registered in the application program that is being executed. By contrast, in the case where the determination result in step S44 is positive, a process of step S46 described later is executed. In the case where the determination result in step S44 is negative, a process of step S45 described later is executed.

In step S45, the application unit 31 determines whether or not the series ID acquired in step S43 matches the series ID to be set for the application program that is being executed. In the application program, information on the series ID to be set for the application program is registered in advance. Therefore, the application unit 31 determines whether or not the series ID acquired in step S43 matches the series ID registered in the application program that is being executed. In the case where it is determined in step S45 that the two series IDs match each other, it is found that the character represented by the figure ID stored on the tag 2 is a character registered in the series to which the application program belongs (although not registered in the application program). In the case where the determination result in step S45 is positive, the process of step S46 described later is executed. By contrast, in the case where the determination result in step S45 is negative, a process of step S47 described later is executed.

In step S46, the application unit 31 executes a process of causing the character represented by the figure ID to appear in the virtual space. In the case where the application unit 31 knows the character represented by the figure ID stored on the tag 2 (in the case where the figure ID is registered in the application program, namely, in the case where the determination result in step S44 is positive), the application unit 31 can cause the character to appear in the virtual space by use of the information in the application program thereof. Namely, the application unit 31 generates the character in the virtual space by use of the information in the application program thereof.

By contrast, in the case where the application unit 31 does not know the character represented by the figure ID stored on the tag 2 (in the case where the figure ID is not registered in the application program, namely, in the case where the determination result in step S44 is negative and the determination result in step S45 is positive), the application unit 31 cannot cause the character to appear in the virtual space by use of the information in the application program thereof. Therefore, the application unit 31 uses the figure ID acquired from the tag 2 to specify the character represented by the figure ID and causes the specified character to appear in the virtual space. For example, the application unit 31 accesses an external server, transmits the figure ID acquired from the tag 2 to the server, and receives data on the character transmitted from the server in response thereto (data for generating the character). In the case where the application program that is being executed is a specific application program, the data for generating the character may be included in the saved data so that the application unit 31 can generate the character by use of the saved data.

The process of step S46 of causing the character to appear in the virtual space may be different between the case where the application program that is being executed is a specific application program and the case where application program that is being executed is a non-specific application program. For example, in the case where the application program that is being executed is a specific application program, the application unit 31 may display the entirety of the character represented by the tag 2 (displays the character as it is) on the display unit 17. By contrast, in the case where the application program that is being executed is a non-specific application program, the application unit 31 may display only a part of the character (e.g., the hat or the clothes of character represented by the tag 2 may be attached to another character). Alternatively, in the case where the application program that is being executed is a specific application program, the application unit 31 may display the character represented by the tag 2 on the display unit 17 in a normal display manner. By contrast, in the case where the application program that is being executed is a non-specific application program, the application unit 31 may display the character in a display manner different from the normal display manner (e.g., display the character as a two heads high figure).

In step S47, the application unit 31 notifies the user that the tag 2 is not usable in (does not correspond to) the application program that is being executed.

After step S46 or S47, the application unit 31 executes the process of step S1 again. After this, the series of processes shown in FIG. 12 are repeated until a condition for terminating the game is fulfilled (e.g., until the user issues an instruction to terminate the game).

3. Functions and Effects of the Example Embodiment

As described above, in the example embodiment, the tag 2 includes a storage unit that stores application data that is usable in a specific application program (dedicated data) and shared data usable in an application program regardless of whether or not the application program is a specific application program. The communication control unit 32 accepts an instruction regarding data read/write from/to the tag 2 from the application program to be executed by the information processing device 3. In the case where the accepted instruction is regarding the dedicated data (e.g., instruction to read the dedicated data), under the condition that the instruction is from a specific application program (step S5: Yes), the communication control unit 32 transfers the dedicated data read from the tag 2 to the specific application program (step S6). In the case where the accepted instruction is regarding the shared data (e.g., instruction to read the shared data), the communication control unit 32 transfers the shared data read from the tag 2 to the specific application program that issued the instruction regardless of whether or not the instruction is from a specific application program (steps S6, S7).

Therefore, according to the example embodiment, the tag 2 is usable to use the dedicated data in the specific application program, and is also usable to use the shared data in an application program that is not limited to the specific application program. Owing to this, the number of applications that can use the tag 2 is increased, and thus the tag 2 can be used in a more versatile manner. The shared data is usable in another application program other than the specific application program as well as in the specific application program, whereas the dedicated data can be restricted from being used in the another application program. Therefore, fraudulent use of the dedicated data in the another application program can be prevented.

In the example embodiment, the tag 2 stores the identification information set for each type of tag (figure ID). The specific application program includes the figure ID set for the tag that stores the dedicated data usable in the specific application program itself. The communication control unit 32 determines whether or not the accepted instruction is from the specific application program based on the figure ID read from the tag 2 and the figure ID acquired from the application program. Owing to this, it can be determined easily whether or not the accepted instruction is from the specific application program.

For making the above-described determination by use of the figure ID, the specific application program may access only a predetermined type of tag among the tags usable in the specific application program itself. Namely, the specific application program may transmit, to the communication control unit 32, the figure IDs of all the tags usable in the application program itself, so that the specific application program can access an optional tag usable in the specific application program itself. Alternatively, the application program may transmit, to the communication control unit 32, a part of the figure IDs of the tags usable in the application program itself, so that the specific application program can limit the tag(s) accessible by the specific application program itself among the tags usable in the specific application program itself. In this manner, for executing the specific application/non-specific application determination process by use of the figure ID, it can be determined whether or not the tag connected to the information processing device 3 is permitted to be accessed by the specific application program, in addition to determining whether or not the application program that has issued the instruction is a specific application program.

In the example embodiment, the tag 2 stores the shared data that is on the object (character) appearing in a predetermined application program (specific application program) and is usable in the specific application program or a non-specific application program. For executing the specific application program, the information processing device 3 uses the shared data read from the tag 2 and thus executes a first process of displaying the object on the display unit 17 (process of displaying the entirety of the character) (step S46). For executing an application program that is not the specific application program (non-specific application program), the information processing device 3 uses the shared data read from the tag 2 and thus executes a second process different from the first process (executes a process of displaying another character wearing the clothes of the above character) (step S46).

According to the above, the tag 2 is usable to use the shared data in the predetermined application program and also in another application program. Owing to this, the number of applications that can use the tag 2 is increased, and thus the tag 2 can be used in a more versatile manner.

The first process and the second process are not limited to being a process of displaying an object, and may be an optional process of outputting information on the object. The information on the object may be, for example, an image representing the object, or a sound on the object (voice or theme tune of the character). In the case where, for example, a theme tune is set for the character represented by the tag 2, the first process and/or the second process may be a process of outputting the theme tune from the speaker (e.g. as BGM).

When near field communication is made possible between the communication control unit 32 and a certain tag 2, the communication control unit 32 determines whether or not the tag is a permitted tag, an access to which by the application program to be executed by the information processing device 3 is permitted (step S3). In the case where it is determined that the tag with which near field communication is made possible is a permitted tag, the communication control unit 32 executes a process in conformity to the instruction (read instruction, etc.) from the application program to be executed by the information processing device 3 (steps S6, S7). In other words, the communication control unit 32 permits the shared data to be used in the application program to be executed by the information processing device 3 under the condition that the tag with which near field communication is made possible is a permitted tag. Owing to this, data on the permitted tag is usable in another application program different from the specific application program, whereas the another application program can be prevented from reading data from a tag that is not a permitted tag.

In the example embodiment, the information processing device 3 executes, as the second process, a process of displaying an object (character) displayed in the first process in a manner different from in the first process (e.g., displays only a part of the object, or displays the object as a two heads high figure) (step S46). Owing to this, the object can be displayed in a display manner suitable to the application, and thus the versatility of the tag (versatility of the data stored on the tag) can be further improved.

In another embodiment, when executing a game application program different from the predetermined application program (non-specific application program), the information processing device 3 may execute a process that does not influence the progress of the game as the second process. For example, as described in the above embodiment, the information processing device 3 may execute a process of changing only the appearance of a character different from the character represented by the tag 2 (e.g., changing the clothes) but not changing a game parameter that influences the progress of the game (e.g., parameter of the strength of the character, etc.). As can be seen, the second process may use the shared data in a supplementary manner unlike the first process. This allows a developer of the application program to make the shared data usable in a more versatile manner in the second process, and thus the versatility of the tag is improved.

In the example embodiment, the tag 2 has an external appearance that represents, three-dimensionally (or two-dimensionally), the object (character) appearing in the virtual space that is generated by execution of a predetermined application program (specific application program) by the information processing device 3 (FIG. 2). The tag 2 stores first identification information (figure ID) on the object and second identification information (series ID) on the group to which the object belongs. The information processing device 3 uses the figure ID read from the tag 2 to execute a predetermined process (process of displaying the character represented by the figure ID (step S46)) and also uses the series ID read from the tag 2 to execute the predetermined process.

According to the above, the application program to be executed by the information processing device 3 can execute the predetermined process by use of either the figure ID or the series ID. Namely, even in the case where the figure ID is not usable (the figure ID is not registered), the series ID can be used to execute the predetermined process (as long as the series ID is registered). As can be seen, the example embodiment allows the application program to execute the predetermined process more easily and allows the tag to be used more easily by a larger number of applications. Thus, the versatility of the tag is improved.

While executing the application program, the information processing device 3 determines whether or not the figure ID read from the tag 2 represents the value registered in the application program that is being executed (step S44). The information processing device 3 also determines whether or not the series ID read from the tag 2 represents the value registered in the application program that is being executed (step S45). The predetermined process (step S46) is executed in the case where at least one of the figure ID and the series ID read from the tag 2 represents the value registered in the application program that is being executed (FIG. 12). Owing to this, as long as one of the figure ID and the series ID is registered in the application program, the application program can execute the predetermined process. This allows the tag to be used more easily by a larger number of applications. Thus, the versatility of the tag is improved.

In the example embodiment, the predetermined process is a process regarding the object (character). In the case where the figure ID read from the tag 2 represents the value registered in the application program that is being executed, the information processing device 3 specifies the object by use of the figure ID (step S46). In the case where the figure ID read from the tag 2 does not represents the value registered in the application program that is being executed (step S45: No) and the series ID read from the tag 2 represents the value registered in the application program that is being executed (S45: Yes), the information processing device 3 specifies the object by use of the series ID. Owing to this, even in the case where the figure ID is not usable, the object can be specified by use of the series ID, and the predetermined process regarding the object can be executed.

4. Modification Examples Modification Example of the Specific Application/Non-Specific Application Determination Process

In the above example, the determination in the specific application/non-specific application determination process is executed by use of the figure ID. In another embodiment, the determination may be executed by use of the use ID described above. Hereinafter, a modification example in which the specific application/non-specific application determination process is executed by use of the use ID will be described.

In this modification example, for reading or writing the dedicated data from or to the tag 2, the application unit 31 first causes the use ID to be included in an instruction (read instruction, write instruction, etc.) and transmits the instruction to the communication control unit 32. Namely, the application program includes information on the use ID to be set therefor. When issuing an instruction to the communication control unit 32, the application unit 31 transfers (outputs) an instruction including the use ID to the communication control unit 32. Owing to this, the communication control unit 32 can acquire the use ID of the application program. The application unit 31 may transfer the use ID to the communication control unit 32 at an optional timing. For example, in another embodiment, the communication control unit 32 may request the application unit 31 for the use ID in the specific application/non-specific application determination process, and in response to the request, the application unit 31 may transmits the use ID to the communication control unit 32.

In another embodiment, the communication control unit 32 may specify the use ID by use of a table that associates an application ID specific to an application program (different from the use ID) and the use ID set for the application program regarding each of the application programs. Namely, the communication control unit 32 may store the table in advance, acquire the application ID together with the read instruction from the application unit 31, and determine that the use ID associated with the acquired application ID as the use ID of the application program.

In the specific application/non-specific application determination process, the communication control unit 32 compares the use ID acquired together with the instruction from the application unit 31 against the use ID read from the tag 2 in step S2. In the case where the use IDs match each other, the communication control unit 32 determines that the application program that issued the instruction is the specific application program. By contrast, in the case where the use IDs do not match each other, the communication control unit 32 determines that the application program that issued the instruction is a non-specific application program.

As in the modification example described above, the tag 2 may store at least one type of identification information specifying the specific application program that can use the dedicated data (use ID). The communication control unit 32 accepts the use ID, corresponding to the application program that issued the instruction, from this application program. The communication control unit 32 determines whether or not the accepted instruction is from the specific application program based on the use ID stored on the tag 2 and the use ID acquired from the application program that issued the instruction (step S5). Owing to this, it can be easily determined whether or not the accepted instruction is from the specific application program.

(Modification Example in which a Free Data Area is Set on the Tag)

In another embodiment, the tag 2 may include a free data area in addition to the data areas shown in FIG. 3 (dedicated data area, shared data area, and management data area). Hereinafter, with reference to FIG. 13, an example in which a free data area is set on the tag 2 will be described as an example of the above embodiment.

FIG. 13 shows an example of data stored on the tag 2 in a modification example of the example embodiment. As shown in FIG. 13, in this modification example, a free data area is set in the read/write area 22 of the tag 2. The free data area is an area to which an application program other than the specific application program (non-specific application program) can write data. At the time of shipping of the tag 2, no data is basically stored in the free data area. In the case where, for example, game data is to be provided as a benefit to a user who purchases the tag, some data may be stored in the free data area.

The application unit 31 that executes a non-specific application program writes data (saved data) to the tag 2 as follows. First, the application unit 31 transmits a write instruction to the communication control unit 32. Like in the specific application/non-specific application determination process in the above modification example, the write instruction includes the use ID of the application program. In response to the write instruction, the communication control unit 32 executes processes substantially the same as those in the above embodiment (steps S1 through S6, S31) (in step S5, the communication control unit 32 executes a process substantially the same to that in the specific application/non-specific application determination process using the use ID in the above modification example). Namely, the communication control unit 32 accesses the tag 2, reads the data and transfers the read data (shared data) to the application unit 31. The application unit 31 transfers the saved data to be written to the tag 2 to the communication control unit 32.

Upon receipt of the saved data from the application unit 31, the communication control unit 32 writes the use ID acquired together with the write instruction and the received saved data to the tag 2 in the state where the use ID and the saved data are associated with each other (FIG. 13). In the tag 2, the data to be written and the use ID may be associated with each other in an optional method. For example, a method by which the free data area is managed as being divided into a plurality of blocks may be used. One block includes a data area to which the saved data is to be written and an ID area to which the use ID of the application program corresponding to the saved data is to be written. The communication control unit 32 writes the saved data to the data area of one block and also writes the use ID to the ID area of the block. As a result, the saved data and the use ID are stored as being associated with each other. Depending on the data size of the saved data, the communication control unit 32 may write the data to two or more blocks. In this case, the same use ID is written to the ID area of each of the blocks to which the saved data is written.

In this modification example also, the update data may be updated at the timing when the saved data is written, like in the above embodiment.

The application unit 31 that executes a non-specific application program reads the saved data from the tag 2 as follows. The application unit 31 transmits a read instruction to the communication control unit 32. Like in the above modification example, the read instruction includes the use ID of the application program. In response to the read instruction, the communication control unit 32 executes processes substantially the same as those of steps S1 through S4.

In this modification example, in the case where it is determined that the tag 2 is not a permitted tag in the access permission/non-permission determination process in step S3 in the above embodiment, the communication control unit 32 executes the following determination process as the specific application/non-specific application determination process in step S5. The communication control unit 32 determines whether or not the use ID included in the read instruction matches the use ID stored in the free data area of the tag 2. The determination process is executed in order to determine whether or not the application program that issued the read instruction is the application program corresponding to the saved data in the free data area of the tag 2.

It is determined that the two use IDs match each other in the determination process, the communication control unit 32 transfers the shared data and the saved data stored in association with the matching use IDs to the application unit 31. Owing to this, the application program that wrote the saved data to the free data area of the tag 2 can read the saved data from the tag 2. By contrast, in the case where the two use IDs do not match each other, the communication control unit 32 transfers the shared data (only the shared data) to the application unit 31.

As described above, in another embodiment, an application program other than the specific application program may be allowed to write the data to the tag 2. Namely, the tag 2 may include a storage area (dedicated data area) from/to which data can be read/written by the predetermined application program (specific application program), a storage area (shared data area) from which data can be read by an application program regardless of whether or not the application program is the predetermined application program, and a storage data (free data area) to which data can be written by an application program regardless of whether or not the application program is the predetermined application program. Owing to this, the number of types of application programs that can write data to the tag 2 is increased. Thus, the versatility and the convenience of the tag 2 can be further improved.

In the above modification example, the communication control unit 32 writes data to the free data area of the tag 2 in response to an instruction to the application program as follows. The communication control unit 32 stores the data to be written and the use ID of the application program on the tag 2 in the state where the data and the use ID are associated with each other. When accepting, from the application program, a read instruction on the data stored in the free data area, the communication control unit 32 determines whether or not to transfer the data to the application program based on the use ID included in the accepted read instruction and the use ID that is associated, with the data to be read, in the free data area of the tag 2. Owing to this, the data stored in the free data area of the tag 2 can be managed to be read by the application programs corresponding to the data (application program that wrote the data and application program for which the same use ID as that of the former application program is set).

In the above modification example, the data (and the use ID) written to the free data area may be allowed to be deleted by the information processing device 3. For example, in response to an instruction from the system application program that received a delete instruction, the communication control unit 32 may delete the data indicated by the delete instruction from the tag 2. Owing to this, even when the free data area of the tag 2 becomes full, a new free area can be generated so that another piece of data can be written. In another embodiment, the tag 2 may store information indicating whether or not the data stored in the free data area can be deleted, in the state where the information is associated with the data.

(Modification Example Regarding the External Appearance of the Tag)

In the above embodiment, the tag 2 is a figure-type tag that represents a character three-dimensionally. The shape of the tag is not limited to this, and the tag may have an optional shape. For example, the tag 2 may be a card-type tag on which a picture of the character is drawn (tag which represents the character two-dimensionally). As can be seen, the tag may have an external appearance that represents, three-dimensionally or two-dimensionally, an object appearing in a predetermined application program (in other words, an object represented by the data stored on the tag (dedicated data and/or shared data)). Owing to this, an object that can be cause to appear in an application by use of the tag 2 is recognizable by the user in an easy-to-understand manner. In the case where the object is displayed on the display unit 17, the user feels as if a real object appeared in the virtual space. Thus, the application can be more entertaining.

(Modification Example Regarding the Shared Data)

In the above embodiment, FIG. 3 shows an example of data included in the shared data. The data included in the shared data is optional. In another embodiment, the initial registration data may include data on a message input by the user. The message is, for example, read by the application program executed by the information processing device 3 and displayed on the display unit 17.

For example, the initial registration data may include identification information on the user of the information processing device 3. The identification information on the user is, for example, a user ID on a network service using the information processing device 3 (e.g., service providing an application via a network). When, for example, the user accesses an information processing device available outside his/her house by use of a tag, the information processing device reads the ID of the user from the tag and notifies the server that the user accessed the information processing device. In this manner, the server can manage the information processing device accessed by the user by use of the tag. For example, an information processing device may be installed at the venue of an event. When the user accesses the information processing device by use of the tag, the server learns that the user is participated in the event. For example, the server may provide the user with a predetermined service or benefit on the network service in response to the notification from the information processing device.

In the above embodiment, the update data includes information regarding the write to the tag 2 (number of times of write, last-write device, number of times of device change, last-used application, and last-write date/time). In another embodiment, the update data may include information on the read from the tag 2. For example, the update data may include information such as the number of times of data read from the tag 2 (number of times the tag has been accessed), the information processing device that read data from the tag 2 most recently, the number of times the information processing device that read the data has been changed, the application program that read data from the tag 2 most recently, the date/time when the data read from the tag 2 was performed most recently, and/or the like.

In the above embodiment, information on the most recent write to the tag 2 (last-write device, last-used application, and last-write date/time) is included in the update data. In another embodiment, the update data may include information on the history of the data write to the tag 2. For example, the update data may include information on the history of the information processing devices that wrote data to the tag 2 (the data may be dedicated data), the history of the application programs that wrote data to the tag 2 (the data may be dedicated data), and/or the history of the date/time when the data was written to the tag 2 (the data may be dedicated data). In still another embodiment, information on the history of the data read from the tag 2 may be included in the update data.

For example, in another embodiment, the information processing devices that wrote data to the tag 2 may be managed as being divided into a “home” information processing device and an “away” information processing device, by use of the update data. The “home” information processing device is the information processing device that wrote the initial registration data, and is typically the information processing device possessed by the user. The “away” information processing device is an information processing device other than the “home” information processing device, and is typically an information processing device possessed by a friend of the user or an information processing device installed in a store or at a venue of an event. The update data may include the number of times of write made by the “home” information processing device and the number of times of write made by the “away” information processing device. Owing to this, an information process suitable to the state of use of the “home” information processing device and the “away” information processing device can be executed.

In another embodiment, the update data may include flag data that is set “ON” when a predetermined condition is fulfilled. The predetermined condition is that, for example, a specific information processing device installed in a store or at a venue of an event accesses the tag. Namely, the flag data stored on the tag 2 is updated to a value representing “ON” by the specific information processing device. Owing to this, information indicating that the user visited the store or the event is stored on the tag. Therefore, the application program can execute a process using such information (e.g., process of providing a benefit to the user who visited a specific event).

(Modification Example Regarding the Structure of the Information Processing System)

In another embodiment, in the case where the tag 2 includes an information processing unit, a part of the process which would otherwise be executed by the information processing device 3 may be executed on the tag 2 side. For example, the process which would otherwise be executed by the communication control unit 32 (a part of, or the entirety of, the process) may be executed by the information processing unit of the tag 2. In the above embodiment, the communication control unit 32 actually reads dedicated data from the tag 2 and manages the transfer of the dedicated data to the application unit 31, and thus the read of the dedicated data from the tag 2 by the application unit 31 is restricted. By contrast, in the case where the process which would otherwise be executed by the communication control unit 32 is executed on the tag 2 side, the read of the dedicated data from the tag 2 by the information processing device 3 is literally restricted.

The systems, devices and apparatuses described herein may include one or more processors, which may be located in one place or distributed in a variety of places communicating via one or more networks. Such processor(s) can, for example, use conventional 3D graphics transformations, virtual camera and other techniques to provide appropriate images for display.
